Question about Samsung HCM5525W 55" Rear Projection Television
Hi, this looks like an excellent forum for techs. I am a big DIY, but never attempted TV repair. Well here's my problem:
I just adopted a TV from a friend, and it is messing up on me. It starts up just fine (maybe a little green tint, but almost not noticeable). However after 30 minutes (around 45 minutes), the tv clicks and the tv gets all hazy. I'm including some pictures so you can see the difference between my startup case and the case where it gets hazy. If you have somewhere I can start, I'll gladly attempt it on my own. Let me know if there is any safety concerns I should be worried about as well. Thanks!
These are two variable resistors has some glue on it for protection, means NOT to adjust it as already adjusted in factory.
now regarding pulling two wires, one thick wire can be pulled ( not in all cases) as shown in below picture. Push it and rotate it. If this not works, don't pull it force ly. just go to other end of this wire and try this method.
LOL, my drawing isn't good :P

Do you hear any wierd sound when its hazy ? Try muting the TV and see.
From your description it sounds to me like voltage fluctuations.
If not externally, it might be internally.
Since this happens after a while, I believe this problem should be associated with a capacitor.
There should be a faulty capacitor inside which needs to be replaced. This is safe to be done by a technician.
And yea, it does not sound safe to use the TV when this happens.
if you still want to go by "DIY".
Try opening the TV and look for any burnt capacitor inside.
